I made this overdrive pedal for Eric, who plays guitar in O Pioneers!!!. Eric also runs an awesome silkscreen shop called Night Owl's Prints. He also made my stickers.

The circuit is an overdrive based on a Tubescreamer with a 4th control, VOICE, to regulate the amount of gain and treble in the circuit. The clipping is asymmetrical provided by three Bat 41 diodes and two 2n7000 MOSFETs. I used madbean's Serendipity PCB project.

The pedal is painted in automotive white enamel. Eric provided the graphic. I used white Davies 1510 knobs and a water clear red LED.
